Lead-zinc are widely used in the electrical, mechanical, military, metallurgical, chemical, light, and pharmaceutical industries. In addition, lead metal also has many uses in the nuclear industry, petroleum industry, and other sectors. Lead and zinc usually coexist in nature, so the mining and beneficiation of lead and zinc ores often need to consider the extraction of these two metals simultaneously. The purpose of lead and zinc ore beneficiation is to maximize the recovery of valuable metals and minimize the generation of waste. By designing and optimizing reasonable crushing, grinding, flotation, concentration and dewatering process, the industrial utilization and efficient recovery of lead and zinc resources can be achieved. Next, we will analyze these four processes!
